Can't get the front axle half shaft in on a case 580 sle wheel digger

Rebuilding them consists of new U joints and maybe balanced. If it was so loose the the u joints wallowed out the keepers, Then yes, they would also need replaced. Cut off and welded on. That isn't a common problem, but I have had to replace a few. Not just on jeeps.

you have to pull the half shaft out on the side the seal is leaking then pop out the seal and install new seal. this means r&r the wheel, brake, separate the lower ball joint, remove the half shaft axle nut, remove the half shaft from the spindle and pull out half shaft from trans. install in reverse order.

The Selectable Four Wheel Drive (S4WD) Front Axle consist of the following components:
• Differential Carrier Housing
• Differential Case Assembly
• Inner Axle Shaft
• Intermediate Shaft Bearing Assembly (located on the right side of the oil pan)
• Electric Motor Actuator
The front axle on Selectable Four Wheel Drive (S4WD) model vehicles uses a disconnect feature mounted on the right side of the oil pan in order to engage and disengage the front axle. When the driver engages the 4WD system, the Transfer Case Control Module sends a signal to the electric motor actuator to energize and extend the plunger inside. The extended plunger moves the clutch fork and clutch fork sleeve across from the clutch fork outer gear that is splined to the right side wheel drive shaft to the clutch fork inner gear that is splined to the inner axle shaft. The locking of the two gears allows the axle to operate in the same manner as a semi-floating rear axle. A propeller shaft connects the transfer case to the front axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the carrier. The axle identification number is located on top of the differential carrier assembly or on a label on the bottom of the right half of differential carrier assembly. The wheel drive shafts are completely flexible assemblies consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a wheel drive shaft.

How To Install Repair Replace 4x4 Front Axle Actuator Chevy Trailblazer...

I AM ASSUMING YOUR VEHICLE IS A FRONT WHEEL DRIVE. SINCE IT IS AN IMPORT THE BOLT WILL BE METRIC AND AT LEAST A GRADE 5 BOLT TO THE AXLE HALF SHAFT. YOU HAVE TWO AXLES ONE LEFT AND ONE RIGHT UNLESS YOU HAVE A REAR WHEEL DRIVE NISSAN. EASY SOLUTION- GOTO YOUR LOCAL NISSAN DEALERSHIP AND GIVE THEM THE YEAR AND MODEL AND TELL THEM WHAT PART YOU NEED AND THEY WILL PULL THE CORRECT PART FROM THEIR PARTS SHELF. WORST CASE SCENARIO- GO TO A WRECKING YARD AND FIND THE SAME MAKE AND MODEL VEHICLE AND HAVE THEM GET THE BOLT FOR YOU. I HAVE A FEELING WHEN YOU SAID( BULB) IN YOU INQUIRY IT WAS JUST A TYPO ERROR.

Most probably a problem with the differential. Best solution would be remove it from its case and repair it.

YOU NEED A PULLER ON THE OUTSIDE WHEEL HUB PUSHING THE HALF SHAFT FROM THE FRONT HUB,THEN TAP THE SHAFT UNION AT THE JOINT CASE WITH A PLASTIC HAMMER TO REMOVE THE HALFSHAFT AND INNER SHAFT FROM THE TRANSAXLE. IF YOU HAVE AN INNER SHAFT REMOVE THE HALFSHAFT BY SETTING UP A PULLER ON THE OUTSIDE WHEEL HUB AND PRESSING THE HALFSHAFT FROM THE FRONT HUB. AFTER PRESSING THE OUTER SHAFT INSERT A PRYBAR BETWEEN THE TRANSAXLE CASE AND THE HALFSHAFT AND PRY THE HALF SHAFT FROM THE TRANSAXLE DONT PULL ON THE SHAFT.

SOUNDS LIKE A BAD HUB TRY THIS TO DIAGNOSE THE PROBLEM

Put the transmission in park, set the parking brake and raise the chassis so one of the front wheels is off the ground while the other is still on the ground. When the transfer case is in two-wheel drive, the hubs should be released allowing the wheels to turn freely when spun by hand. If the axle shaft turns when you spin the wheel, it means the hub has not disengaged.
To check engagement, rotate the axle shaft backwards. This should lock the hub. Try turning the wheel by hand again. The axle shaft should now turn with the wheel if the hub is locked. If the hub fails to lock, the hub will have to be disassembled and inspected or replaced.
To check release, hold the axle shaft steady and rotate the wheel backwards. You should hear a click as the locking mechanism slides back out and disengages the hub. Rotate the wheel forward again and it should turn freely.
Another way to check the hubs is to raise the vehicle on a frame contact lift so all four wheels are off the ground. Then start the engine and place the transfer case in four-wheel drive and the transmission in drive. If the front wheels don't turn, look at the front axle shafts. If both shafts are turning, but one wheel is not, the problem is a bad hub on the wheel that isn't turning. If the front driveshafts are not turning when the transfer case is in four-wheel drive, the problem is inside the differential (broken side gears) or the transfer case (broken chain, shift linkage, etc.). If the driveshaft between the transfer case and differential is turning, the problem is in the differential. If the driveshaft is not turning, the vehicle is going to need repairs to the transfer case.
Hope this helps.

the front axles have pinon gear box that the shaft from the transfer case goes to, it has a vacuum hose to it or a solenoid actuator check these for proper function this is how the power is turned on to the wheels.

After lifting, carefully pry calipers back (slightly) just enough so front wheel will spin freely. Remove speedometer cable at wheel (if you have one). Then, put a phillips screwdriver through hole in front axle (this just gives you something to pull the axle out with). Then remove the big axle nut. Then remove the lower axle half-clamps. These are the little nuts on bottom. Some forks only have one, & if this is the case, then use the phillips to pull the axle out sideways while supporting tire. Assembly is the reverse of this procedure.

Hi.. The step to remove the front Axles of you Vitara.
Raise and support Vehicle . Remove front wheel,
Drain Diff,fluid,
Remove Locking Hub if is equipaded,
Remove Circle clip from axle shaft
On right side of Vehicle, Remove the Stabilizer Little ball joint nut. Remove castle nut Front Tie rod end,
Remove mounting bolts from brake calipper,
Remove Calipper from steering knuckle and wire a side.
Remove Stud Nut from steering knuckle,
Support Lower suspension arm with a jack,
Remove lower strut bracket bolt ,
Lower jack and disconnect Knuckle from lower suspension crontrol arm,
Pull Outler joint from Hub.
Use Large screwdriver or Prybar To pry Right inner joint from differential, The axle will go out making a little froce with the prybar,
To remove the left side,
Remove mounting bolt from inner joint flange,
Pull out axle from hub.

To reinstall just reverse the prosses.

I hope this help on your job...
Thank you for use fixya....
